Greetings! I recently bought a 1937 Desoto rumble seat coupe, looks mostly complete but the engine is seized and in pieces so I would like to find a bolt in replacement engine for now. I found a 1951 Desoto engine with a S15 stamp on the block. Would this engine be a bolt in replacement for my 1937 engine? Main concerns are will the large plate style 1937 front engine mount work and will my 1937 transmission work with the engine. I have the 1937 parts from the flywheel back available.
Also is there reference material anywhere that explains the differences between the Dodge/Chrysler/Desoto flat sixes as far as interchange?
